Hi, we’ve got a jack Russell fox terrier, she’s 10, beautiful and healthy, but a bit terratorial, she loves certain people like a puppy, and dislikes others with no apparent reason, we’ve just had a little baby boy, and we are both worried that when he’s toddling, he may grab her or poke her and she’ll go for him, she’s nipped people before, I really don’t want to lose her but we are both so worried, can anyone help!!
